TROLLEY.

Specification of Letters Patent.

Patented Sept. 7, 1915.

Application filed November 24, 1914. Serial No. 873,698.

To all whom it-may concern:

Be it known that I, VVILLIs F. BEAM, a citizen of the United States of America, residing at Seanor, in the county of Somerset and State of Pennsylvania, have invented certain new and useful Improvements in Trolleys, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to trolleys and has for its object to provide a device of such class, in a manner as hereinafter set forth, which is simple in its construction and arrangement, strong, reducing to a minimum the wedging in the frog or catching upon the trolley wire.

A further object of the invention is to provide a trolley, with means in a manner as hereinafter set forth, whereby the current is direct from the harp to the trolley parts as hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto'appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views :Figure l is a side elevation of a trolley in accordance with this invention. Fig. 2 is a perspective view of the pole head. Fig. 3 is a like view of the harp.

Referring to the drawings in detail 1 denotes a pole head body, which is bifurcated as at 2, thereby providing a pair of arms 3,

' 4, which are mounted upon the pole, not

purpose of fixedly securing said arms 3, 4,

to the pole. I The body portion 1 is formed with a longitudinal lug 6, having an opening 7 adapted to receive a trolley cable,and the upper part of said body portion 1 is offset as at 8, and said offset portion 8 is cut away to form an arm 9, provided with an opening 10. The cutting away of the offset portion 8 forms a seat 11, and an over-hanging lug 12. The seat 11 is curvilineal. A portion of the lug 12 is formed with a curvilineal seat 13.

The harp consists of a base 14 having formed integral therewith a pair of arms 15, 16, which are connected together by a curvilineal coupling portion 17. The arms 15, 16, are formed integral with the sides of the base 14 and project from the upper face of said base, as well as from the forward end thereof. The free ends of each of the arms 15, 16 are thickened as at 18 and a'pertured as at 19 and said thickened endportions 18, form shoulders 20. Each of the thickened end portions 18 is formed with an opening 21 which intersects the opening 19. The lower portion of the base 14 projects from the coupling portion 17, and is cut away to form a pair of extensions 22, 23, the latter being of less length than the former, as well as being spaced from the same. The cutting away of the base to provide the extensions 22, 23, form an opening 24, having one end thereof rounded as at 25. The base 14 in proximity to the coupling portion 17 is formed with a rectangular opening 26 and the extension 22 is formed with an opening for the passage of a threaded bolt 27. The extension 22 has anapertured lug 28 adapted to receive the end of a trolley cable.

Mounted in the openings 19 is a shaft 29, which carries a trolley wheel 30, and said shaft is provided with openings, which register with the openings 21, and extending through said registering openings are cotter pins 31 for connecting the shaft to the arms 15, 16 of the yoke. By such an arrangement if one of the cotter pins is removed the other cotter pin will maintain the shaft in the harp. The bolt 27 projects through the extensions 22, 23, and through the opening 10 and the head of the bolt bears against the upper face of the base 14. The lower end of the bolt 27 carries a nut 32, whereby the harp is pivotally connected to the pole head. The curvilineal portions 11, 13, provide bearings for the free end of the extension 23 and the outer face of the curvilineal coupling portion 17, and the curvilineal portion 25 forms a bearing for the free end of the arm or extension 9. The lug 12 overlaps the upper edge of the coupling por tion 17.

What I claim is l. A trolley comprising a pole head formed with an extension, a harp including a base cut away to form a pair of extensions, said extension of said pole head projecting between the pair of extensions of said base, means for pivotally connecting the harp base to said extension, said harp further including a pair of arms connected together by a curvilineal coupling portion, a lug on the pole head adapted to engage and overreach said curvilinear coupling, said arms of the harp being formed integral with one side of said base, projecting from one face and one end of the base, and provided with means for receiving a trolley wheel axle.

2. A trolley, comprising a pole head and a harp pivotally connected therewith and adapted to rock thereon horizontally, the pole head and harp being each provided with a longitudinally extending lug, said lugs spaced from each other and adapted to receive and hold a trolley cable, whereby the resiliency of the cable will serve to yieldingly hold the pole head and harp in longitudinal alinement with each other.

3. A trolley comprising a pole head having an extension, a plurality of seats one above the other, and a lug; a harp including a pair of extensions one above the other and a pair of arms connected together by a curvilinear section, said extensions of the harp being adapted to cooperate with said extension or the pole head, the extension of the pole head extending between the extensions of the harp, the upper one of said harp extensions and said curvilinear section being adapted to cooperate with said seats of the pole head; means for pivotally con necting said pole and harp extensions together; and a trolley wheel journaled in said harp.

In testimony whereof I affix my slgnature 1n the presence of two wltnesses.
